LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 691,632, dated January 21, 1902.

Application filed July 6, 1901.

The object of the invention is to provide an exceedingly simple and efticientdevice by means of which oil will be intermittently fed to the journal or axle, and with this object in View the invention consists in the peculiar construction of the Various parts and their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speci-v fication, Figure l is a perspective view illustrating the exterior of my lubricator. Fig. 2 is a vertical longitudinal sectional view, the axle being shown in elevation. Fig. 3 is a transverse sectional View, and Fig. 4 is an inverted plan view, of a section of the axlebearing.

Referring to the drawings, A indicates the axle or shaft, the end of which is journaled in a suitable boxing or bearing B, which is preferably made in two sections, B and B2, securely bolted together. A box or receptacle C is suitably secured upon the top of the section B2, said receptacle C having a suitable top or cover C. The bottom of the box' or receptacle C is formed with a central up- .Wardly-proj ectin g boss D, which is perforated,

said perforation registering with au opening E, produced in the section B2 of the box or bearing B, and oil-feeding ducts E are produced in the section B2 for the purpose of distributing the oil to the axle or shaft A, it being of course understood that the box or receptacle C is intended to receive the lubrieating-oil. A tapering plug F is fitted in the perforated boss D, said plug having a chain G attached to its upper end, said chain G passing around a wheel H, mounted upon a shaft I, journaled in the ends of the box or receptacle C, and a lever K depends from the outer end of said shaft and is adapted to be Serial No, 67,319. (No model.)

engaged by the tappet-lug L, mounted upon the end of the axle or journal shaft, so that at each revolution `of the said axle or shaft the end of the lever is tapped, rocking the same, and thereby causing the wheel H to vibrate, and through the medium of the chain G the plug F is intermittently raised and lowered, thereby feeding the lubricant throughv the opening E to the axle or shaft. The chain Gr preferably travels over guide-rollers M, mounted in suitable brackets N, attached to the inner sides of the box or receptacle C.

lIt will thus be seen that I provide anexceedingly cheap and simple construction of lubricator which can be applied to any form of journal box or bearing now in use and which will serve to uniformly feed the lubricant to the journal or axle.

Having thus fully described myA invention, what I claim as new, and desire to secure by Letters Patent, is

Y l. The combination with the axle or shaft and the journal box or bearing, said box or bearing having an opening in thetop thereof, of van oil box or receptacle having an opening in the bottom thereof adapted to register with the opening in the top of the journal box or bearing, the rock-shaft and lever, the wheelv and chain, the plug carried by thechain, and adapted to fit the opening in the bottom of the oil box or receptacle, and the tappet-lug arranged upon the end of the axle or shaft, substantially as described.

2. The combination with the axle or shaft, of the journal box or bearing made in two sections, the upper section having an opening produced therein, an oil boxor receptacle ar.- ranged upon the upper section of the journal box or bearing and having an opening inthe bottom thereof adapted to register with the 'opening in the top of tlie journal box or bearing, the plug adapted to open and close the said opening, the chain attached to the plug, the wheel around which the chain passes, the rock-shaft upon which the wheel is'mounted, the rocking lever and the tappet, and the guide-rollers and brackets, all arranged and adapted to operate substantially as described.

THOMAS S. JAMES.
